My first real job, W-2, at 16 in a factory. Started at $1.90/hr. I think minimum wage back then was $1.65/hr. Started in a small 4-person incoming inspection department for a company that made telecom equipment that the public never sees. My job was to check what was on skids that came in from Receiving, look for electronic components, pull a copy of the PO, open up boxes, and take a sampling of parts. An at-random 32 pieces, IIRC. Then test them using whatever test equipment required. If 1 out of the 32 failed to meet specs, then take a bigger sample. If 2 out of 32 failed, reject shipment and write it all up, including rejection papers.
With my abilities, quickly moved on from testing mundane parts, to testing transistors with a $$ HP Curve Tracer. Also spent 10 hours a day every day of my high school spring vacation, testing a zillion shipping tubes of Motorola 1437L DIP-packaged dual op-amps, as Motorola had problems, but we desperately needed good parts to avoid shutting down production. I was methodical, I set up and labeled boxes to be tested, tested good, tested bad, went through thousands of ICs with no errors.
The big QA boss always stopped by to see how I was doing on his way home at evening.
A few months later, the supervisor of the electronic test dept. came over and asked if I could "help out for a bit" in his Dept., which tested and troubleshot/repaired modules from production. That was my new job.
I liked working there, day shift would go home, the place would become very quiet until the "second shift production ladies" came in at 6:30 PM who worked further over.
I too was surprised how much was taken out of my check FICA/FIT/St. taxes. For some reason, I previously thought it would ALL be mine!
I was always interested in mechanical/electrical/electronic things as a child. Took things apart when they were thrown out, wanted to see inside, how did they work. Found most people couldn't care less, wondered why I was doing that. Didn't bother me, I kept on.
Unfortunately, the early to mid 1970s were recession riddled, layoffs, hired somewhere else, etc. while at same time trying to go to college then.
I learned a lot about people and money in factories. Good people who wished they would have gotten an education when they were younger, some very petty "little people", to college-kid haters that were dead-enders in life and thought the blame for that always laid elsewhere than themselves.
One of the lessons learned was for me to go on and get a professional degree from a high-rated University, and never work in a factory again.
That degree, and abilities, opened doors.
